'valign-f v 'i 'i a citizen of the iUnited States, residing at diagrammaaeauy iff the Chicago, in the county 'of' Cook and State of Illinois, have invented a certain new and useful Improvement in Turbines, of which the Efollowing is a Specication. f f

-My vinvention relates toi improvements in turbine wheels and process of producing the same and-has for one, object toprovide a new Land impro/ved' typeA of turbine wheel which will be light, durable and inexpensive to manufacture. 'Other objects of my m vention-will appear in thespecilication.V

The invention is illustrated lmore or less accompanying drawings, wherein- Figure l is a side elevation of a portion of'a turbine wheel; lFig. 2 a section on the line 2 2 of Fig. l; Fig. 3 Ais a plan view of a turbine bucket; Fig. 4 is a section on the line lL-4 thereof; Fig. 5 is a section on the line 5,-5 of Fig. 4; and Fig. 6 is a rear elevation of one of the buckets.

Like parts are indicated by like figures throughout the several figures.

A is a wheel reinforced at A1 mounted on a hub A2 annularly'channeled at its outer periphery A3.

B is a bucket carrying ring substantially concentric with and contained within the channel A3. l

B1 are screws holding the ring removable in the channel.

B2 are buckets strung or mounted on the annular ring having rearwardly extending ears B3 vembracing the ring on either side.

B4 is', a section removablefrom the ring held separately in the channel in line with the remainder of the ring to provide an aperture through which the buckets -may `be inserted on or withdrawn from the ring. The buckets are normally free to slide about the ring but held thereon by rearwardly eX- tending embracing ears. The mounting or bucket ring conforms generally to the contour of the bucket ears and when drawn tight upon the wheel is wedged within the channel or groove and clamps the buckets firmly in position.'

It will be evident that while I have shown in my drawings an operative device, still many changes might be made both in size, shape and arrangement of parts without departing from the spirit of. my invention and "Yarraman, f j

is covered by a series of buckets arranged side by side. The removable section of the ring is also covered and then the ring thus formed and assembled and carrying the buckets separably secured thereon is Separably secured to the rotor or wheel on a face thereofl and lying in its plane of rotation' by the screws as `shown.` These screws 1 being then tightened up clamp the ring to the wheel and clamp the buckets between the ring and the wheel to hold them in iiXed operative relation.

I claim:

l. A turbine including a turbine wheel, buckets for the turbine wheel,` and a mounting ring separably secured to the turbine wheel and to which mounting ring the buckets are separably secured, said buckets having rearwardly extending ears embracing the ring.

2. A turbine including a rotor, turbine buckets, and a mounting ring separably secured to the rotor at a face thereof that lies in the plane of rotation of the rotor and upon which mounting ring the buckets are separably secured to one Side of the rotor, the mounting ring and buckets hav ing interconnection permitting the buckets to be moved alongthe mounting ring, while supportingly engaged therewith, for the purppse of mounting and demounting the bucke s.

3. A turbine including a rotor, turbine buckets and a. mounting ring carried by the rotorgata face thereof that lies in the plane of rotation of the rotor and upon the outer side of which mounting ring the buckets are separably secured to one side of the rotor and ring, the mounting ring and buckets having interconnection permitting the buckets to be moved along the mounting ring, while supportingly engaged therewith, for the purpose of mounting and demounting the buckets.

4. A turbine including a rotor, turbine the rotor at a face thereof that lies in the plane of rotation of the rotor and upon the in the plane of rotation of the rotor and upon the outer side of which mounting ring the buckets are separably secured to one side of the rotor and ring, said buckets having rearwardly extending ears en'ibracing the ring.

G. A bucketwhecl forturbines and the like comprising a wheel body channeled at its outer periphery, a removable ring and means for removably holding it in said channel, a series of turbine buckets removably1 mounted upon said ring, said buckets being held upon said ring by rearwardly extend ing ears which embrace it.

7. A bucket wheel for turbines and the like coniprising a ring, means for attaching it to the wheel and ay series of buckets separably secured to the ring, said buckets having rearwardly extending ears which embrace the ring.

8. A bucket wheel for turbines the like comprising a rotor body channeled near its periphery, a ring and means for removably mounting it in said channel and a series of turbine buckets mounted upon said ring so as to be movable therealong, said parts being constructed and arranged to be complete with but a single ring, said buckets being operatively secured in place by said single ring. y

In testimony whereof I aflix my signature in the presence of two witnesses this 4th day of December, 1914.
